dubbo 多个提供者的api相同怎么处理

Public Const hkey as Long
Public Const reg_sz As Long = 1
Public Const HKEY_LOCAL_MACHINE = &H80000002
Public Const HKEY_CURRENT_USER = &H80000001

Public Declare Function RegCreateKey Lib "advapi32.dll" Alias "RegCreateKeyA" (ByVal hKey As Long, ByVal lpSubKey As String, phkResult As Long) As Long

在指定的项下创建一个新项。如指定的项已经存在，那么函数会打开现有的项

hKey ----------- Long，要打开项的句柄，或者一个标准项名

lpSubKey ------- String，欲创建的新子项。可同时创建多个项，只需用反斜杠将它们分隔开即可。例如level1\level2\newkey

phkResult ------ Long，指定一个变量，用于装载新子项的句柄

Public Declare Function RegSetValueEx Lib "advapi32.dll" Alias "RegSetValueExA" (ByVal hKey As Long, ByVal lpValueName As String, ByVal Reserved As Long, ByVal dwType As Long, lpData As Any, ByVal cbData As Long) As Long ' Note that if you declare the lpData parameter as String, you must pass it By Value.

hKey ----------- Long，一个已打开项的句柄，或指定一个标准项名

lpValueName ---- String，要设置值的名字

Reserved ------- Long，未用，设为零

dwType --------- Long，要设置的数量类型

lpData --------- Any，包含数据的缓冲区中的第一个字节

cbData --------- Long，lpData缓冲区的长度

比如要增加一个启动项目：

dim hkey as long
dim str as string
str="c:\t1.exe"
RegCreateKey HKEY_LOCAL_MACHINE, "software\microsoft\windows\currentversion\run", hkey

RegSetValueEx hkey, "test", 0, reg_sz, ByVal str, len(str)

删除

Public Declare Function RegDeleteValue Lib "advapi32.dll" Alias "RegDeleteValueA" (ByVal hkey As Long, ByVal lpValueName As String) As Long

RegDeleteValue hkey, "test"

没明白可以补充

分组或者用版本号区分
